However, in massive regular room-and-pillar mining, which is used in underground limestone mines, the slashing round only has to be used to start crosscuts
from the most advanced heading.
Drift tunnels have been driven from the crosscut
tunnels either eastwards or westwards along major mineralized structures to test the strike continuity of mineralization zones.
, an ax and simple bow saw are the only tools I have used ever since, for felling, bucking, trimming, cutting notches in log construction or any other homestead uses.
shredders offer tighter security since they shred a sheet of paper into thousands of tiny particles that are difficult - if not impossible - to reconstruct.
The two veins intersected by the crosscuts
are reviewed as follows:
In both the rip-first and the crosscut
-first simulations and for all three grade mixes, the majority of the sawlines were made in the second cut-up stage (the crosscut
stage in the rip-first simulations and the ripping stage in the crosscut
The Stromnes or Atlas Copco long-hole production rigs mentioned above are used to drill a fan-shaped series of blastholes upwards from the central of the three lower crosscuts
along the full width.
For example, if a user wants a disintegrator but really needs only a crosscut
shredder to handle his or her specific data destruction requirements, the vendor should tell him or her so.
A new gold zone occurs at the end of Crossscut B, approximately 35 feet west of new mineralized zone indicated in the next paragraph also for crosscut
This will require the development of crosscuts
and drill stations, and is currently being scheduled for the second quarter of 2006.
The existing 2,000-metre adit and 600 metres of crosscuts
will provide access.
Two of the underground drifts and crosscuts
were designed to test the vertical continuity of the system.
5-meter wide sulfide vein that crosscuts
the breccia returned 9.
New data also allowed us to conclude that hole ELE-05-59 crosscuts
the Roberto zone with an intersection grading 3.
In November and December, 2004 Endeavour released high grade silver assays from North Porvenir in two surface drill holes, eight underground crosscuts
and two pre-production sill levels.
